Animate MakeHuman character with BVH using Three.js
The simplest process to achieve character animations, created from makehuman in Blender is the following:

1. Install makewalk. This is a Blender addon that should be contained in a folder called blendertools in your makehuman folder.



Drag the makewalk folder into your blender addons folder. On windows, it is c:\users*your_name*\appdata\roaming\blender foundation\blender\2.78\scripts\addons



Then, within blender, go to setting, addons, hit the refresh button on the bottom of the window, and search for makewalk, and enable it, then save your settings

2. Install the .mhx2 plugin to export from Makehuman and import into Blender. The addon consists of two seperate parts - one addon for makehuman and one for Blender. 

Download information and instruction on how to install can be found here

3. Create your character in Makehuman, add a mocap skeleton, and export as mhx2, taking note of the setting shown below





4. Import the mxh2 model in blender.

5. Download motionbuilder compatible bvh files. Here is a source with thousands of motion capture files https://sites.google.com/a/cgspeed.com/cgspeed/motion-capture/cmu-bvh-conversion

6. In blender, with the makewalk addon, attach the bvh file to your character's armature.
